240f019d58 fix(hnsw): resolve segfault with parameterized queries (Issue #141)
This commit fixes a critical P0 bug where HNSW indexes on ruvector
columns would crash PostgreSQL with a segmentation fault when using
parameterized queries (prepared statements, ORMs, application drivers).

Root Cause:
- Query vector extraction failed for parameterized queries
- Code fell back to zero vector without validation
- Zero vector caused segfault during HNSW search

Changes:
- Add multi-method query vector extraction pipeline
  1. Direct RuVector::from_polymorphic_datum()
  2. Text parameter conversion for parameterized queries
  3. Validated varlena fallback with dimension checking
- Add query_valid flag to track extraction success
- Add validation before search execution:
  - Reject empty/invalid query vectors with clear errors
  - Reject all-zero vectors (invalid for similarity search)
  - Validate dimension match between query and index
- Apply same fixes to IVFFlat for consistency

Testing:
- Added regression tests for parameterized queries
- Added tests for zero vector error handling
- Added tests for dimension mismatch errors
- Added 384-dimension production-scale tests

Fixes: #141
See: docs/adr/ADR-0027-hnsw-parameterized-query-fix.md

6dff0a17b9 feat(delta-behavior): Complete Δ-behavior implementation with WASM
Implements the full delta-behavior framework - systems where change is
permitted but collapse is not.

## Core Implementation
- Coherence type with [0,1] bounds and safe constructors
- Three-layer enforcement: energy cost, scheduling, memory gating
- DeltaSystem trait for coherence-preserving systems
- DeltaConfig with strict/relaxed/default presets

## 11 Exotic Applications
1. Self-Limiting Reasoning - AI that does less when uncertain
2. Computational Event Horizon - bounded computation without hard limits
3. Artificial Homeostasis - synthetic life with coherence-based survival
4. Self-Stabilizing World Model - models that refuse to hallucinate
5. Coherence-Bounded Creativity - novelty without chaos
6. Anti-Cascade Financial System - markets that cannot collapse
7. Graceful Aging - systems that simplify over time
8. Swarm Intelligence - collective behavior without pathology
9. Graceful Shutdown - systems that seek safe termination
10. Pre-AGI Containment - bounded intelligence growth
11. Extropic Substrate - goal mutation, agent lifecycles, spike semantics

## Performance Optimizations
- O(n²) → O(n·k) swarm neighbor detection via SpatialGrid
- O(n) → O(1) coherence calculation with incremental cache
- VecDeque for O(1) history removal
- SIMD utilities with 8x loop unrolling
- Bounded history to prevent memory leaks

## Security Fixes
- Replaced unsafe static mut with AtomicU64 for thread-safe RNG
- NaN validation on all coherence inputs
- Overflow protection in calculations

## WASM + TypeScript SDK
- Full wasm-bindgen exports for all 11 applications
- High-level TypeScript SDK with ergonomic APIs
- Browser and Node.js examples

## Test Coverage
- 32 lib tests, 14 WASM tests, 13 doc tests (59 total)

Resolves #140

* fix(wasm): fix js-sys Atomics API compatibility

Update Atomics function calls to match js-sys 0.3.83 API:
- Change index parameter from i32 to u32 for store/load
- Remove third argument from notify() (count param removed)

Fixes compilation errors in workers/shared.rs for SharedTensor
and SharedBarrier atomic operations.

* security: comprehensive security hardening (ADR-012)

CRITICAL fixes (6):
- C-001: Command injection in claude_flow_bridge.rs - added validate_cli_arg()
- C-002: Panic→Result in memory_pool.rs (4 locations)
- C-003: Insecure temp files → mktemp with cleanup traps
- C-004: jq injection → jq --arg for safe variable passing
- C-005: Null check after allocation in arena.rs
- C-006: Environment variable sanitization (alphanumeric only)

HIGH fixes (5):
- H-001: URL injection → allowlist (huggingface.co, hf.co), HTTPS-only
- H-002: CLI injection → repo_id validation, metacharacter blocking
- H-003: String allocation 1MB → 64KB limit
- H-004: NaN panic → unwrap_or(Ordering::Equal)
- H-005: Integer truncation → bounds checks before i32 casts

Shell script hardening (10 scripts):
- Added set -euo pipefail
- Added PATH restrictions
- Added umask 077
- Replaced .tmp patterns with mktemp

Breaking changes:
- InferenceArena::new() now returns Result<Self>
- BufferPool::acquire() now returns Result<PooledBuffer>
- ScratchSpaceManager::new() now returns Result<Self>
- MemoryManager::new() now returns Result<Self>

New APIs:
- CacheAlignedVec::try_with_capacity() -> Option<Self>
- CacheAlignedVec::try_from_slice() -> Option<Self>
- BatchVectorAllocator::try_new() -> Option<Self>

Documentation:
- Added ADR-012: Security Remediation

* feat(npm): add automatic model download from HuggingFace

Add ModelDownloader module to @ruvector/ruvllm npm package with
automatic download capability for RuvLTRA models from HuggingFace.

New CLI commands:
- `ruvllm models list` - Show available models with download status
- `ruvllm models download <id>` - Download specific model
- `ruvllm models download --all` - Download all models
- `ruvllm models status` - Check which models are downloaded
- `ruvllm models delete <id>` - Remove downloaded model

Available models (from https://huggingface.co/ruv/ruvltra):
- claude-code (398 MB) - Optimized for Claude Code workflows
- small (398 MB) - Edge devices, IoT
- medium (669 MB) - General purpose

Features:
- Progress tracking with speed and ETA
- Automatic directory creation (~/.ruvllm/models)
- Resume support (skips already downloaded)
- Force re-download option
- JSON output for scripting
- Model aliases (cc, sm, med)

Also updates Rust registry to use consolidated HuggingFace repo.

* feat(benchmarks): add Claude Code use case benchmark suite

Comprehensive benchmark suite for evaluating RuvLTRA models on
Claude Code-specific tasks (not HumanEval/MBPP generic coding).

Routing Benchmark (96 test cases):
- 13 agent types: coder, researcher, reviewer, tester, architect,
  security-architect, debugger, documenter, refactorer, optimizer,
  devops, api-docs, planner
- Categories: implementation, research, review, testing, architecture,
  security, debugging, documentation, refactoring, performance, devops,
  api-documentation, planning, ambiguous
- Difficulty levels: easy, medium, hard
- Metrics: accuracy by category/difficulty, latency percentiles

Embedding Benchmark:
- Similarity detection: 36 pairs (high/medium/low/none similarity)
- Semantic search: 5 queries with relevance-graded documents
- Clustering: 5 task clusters (auth, testing, database, frontend, devops)
- Metrics: MRR, NDCG, cluster purity, silhouette score

CLI commands:
- `ruvllm benchmark routing` - Test agent routing accuracy
- `ruvllm benchmark embedding` - Test embedding quality
- `ruvllm benchmark full` - Complete evaluation suite

Baseline results (keyword router):
- Routing: 66.7% accuracy (needs native model for improvement)
- Establishes comparison point for model evaluation
